Abstract: An internet browsing gateway is utilized to locate mobile web content and improve search capabilities for wireless devices. Mobile browsing data is logged as web pages are requested from and returned to wireless devices associated with the same wireless network. An index server continually updates search indexes in real time as users request searches and search results are returned. As a result, the mobile content that is discovered becomes more relevant for users of the same wireless network or mobile carrier. In other words, the search results are more localized in accordance with the location of the wireless network that services the mobile users within a specific geographic region. When a web search is requested from a wireless device, the index server queries the search indexes. The search results are ranked using a search algorithm that incorporates the browsing data to improve the accuracy and relevance of searches.

Abstract: Methods of reducing high molecular weight species (HMW) formation in a sample containing a protein purified using ion exchange (IEX) chromatography are disclosed, as are a number of related methods, e.g., methods of reducing on-column denaturation of a protein in a protein sample purified using an ion exchange (IEX) column or resin. The methods share characteristics of including arginine, glycine and/or histidine in the buffers used during the ion exchange (IEX) chromatography.
